    • The method is used to create a virtual public numbering domain, which will coexist with and be parallel and non-intrusive to the existing geographic North American telephone network numbering plan. It will have capacity to provide additional and more flexible numbering resources which will stimulate and enable many new service applications. The existing telephone network infrastructure has digital switching points and a database system. The method consists in receiving at one of the digital switching points a called number, and verifying whether the number called is a number of the virtual public dial plan. If the number called is a number of the virtual public dial plan, the next steps consist of forming with the number called a virtual public address of predetermined length, supplying the virtual public address to the database system to determine a corresponding network node address, and of supplying the corresponding network node address to the digital switching point and routing the call through the network infrastructure according to the existing dial plan. If the number called is a number of the existing dial plan, the call is routed through the network infrastructure according to the existing dial plan and the number called.
    • 该方法用于创建一个虚拟公共号码域,它将与现有的北美电话网络编号计划共存并且并行和非侵入。 它将具有提供更多和更灵活的编号资源的能力,这将刺激并实现许多新的服务应用。 现有的电话网络基础设施具有数字交换点和数据库系统。 该方法包括在一个数字交换点接收一个被叫号码,并且验证被叫号码是否是一个虚拟公共拨号计划的号码。 如果所呼叫的号码是虚拟公共拨号计划的数目,则下一步骤包括以称为预定长度的虚拟公共地址的号码形成,向数据库系统提供虚拟公用地址以确定对应的网络节点地址,以及 将相应的网络节点地址提供给数字交换点,并根据现有的拨号计划通过网络基础设施路由呼叫。 如果所呼叫的号码是现有拨号计划的号码,呼叫将根据现有拨号计划和呼叫号码通过网络基础设施进行路由。
